Lenz v. Universal Music Corp. And the Potential Effect of Fair Use Analysis Under the Takedown Procedures of §512 of the DMCA

The notice and takedown/putback procedures in §512 of the Digital Millennium Act fail to adequately protect the rights of individuals who post content on the internet. This iBrief examines the notice and takedown/putback procedures and Judge Fogel\u27s decision in Lenz v. Universal Music Corp., which requires a copyright owner to conduct a fair use evaluation prior to issuing a takedown notice. This iBrief concludes such a requirement is an appropriate first step towards creating adequate protection for user-generated content on the Internet

Radiofrequency Ablation for Post Infarction Ventricular Tachycardia

Radiofrequency ablation has an important role in the management of post infarction ventricular tachycardia. The mapping and ablation of ventricular tachycardia (VT) is complex and technically challenging. In the era of implantable cardioverter defibrillators, the role of radiofrequency ablation is most commonly reserved as an adjunctive treatment for patients with frequent, symptomatic episodes of ventricular tachycardia. In this setting the procedure has a success rate of around 70-80% and a low complication rate. With improved ability to predict recurrent VT and improvements in mapping and ablation techniques and technologies, the role of radiofrequency ablation should expand further

Estimating State-allocable Production Technologies When there are two States of Nature and State Allocations of Inputs are Unobserved.

Chambers and Quiggin (2000) have used state-contingent production theory to establish important results concerning economic behaviour in the presence of uncertainty, including problems of consumer choice, the theory of the firm, and principal-agent relationships. Empirical application of the state contingent approach has proved difficult, not least because most of the data needed for applying standard econometric methods are lost in unrealized states of the world. O’Donnell and Griffiths (2006) show how a restrictive type of state-contingent technology can be estimated in a finite mixtures framework. This paper shows how Bayesian methodology can be used to estimate more flexible types of state-contingent technologies.

Excited multiplets of Eu in GaN

A method to calculate the multiplet states of lanthanide impurities in solids is presented. This approach is based on a semi-empirical density functional method which includes corrections to account for the correlation and spin-orbit coupling of the 4f electrons. Specific multiplet states of the rare earth are produced by constraining the system. This approach is then used to investigate some of the properties of substitutional europium impurities in gallium nitride, reproducing the relative energy of two multiplets, and discussing a potential excitation mechanism for these centers

A composition theorem for the Fourier Entropy-Influence conjecture

The Fourier Entropy-Influence (FEI) conjecture of Friedgut and Kalai [FK96] seeks to relate two fundamental measures of Boolean function complexity: it states that $H[f] \leq C Inf[f]$ holds for every Boolean function $f$, where $H[f]$ denotes the spectral entropy of $f$, $Inf[f]$ is its total influence, and $C > 0$ is a universal constant. Despite significant interest in the conjecture it has only been shown to hold for a few classes of Boolean functions. Our main result is a composition theorem for the FEI conjecture. We show that if $g_1,...,g_k$ are functions over disjoint sets of variables satisfying the conjecture, and if the Fourier transform of $F$ taken with respect to the product distribution with biases $E[g_1],...,E[g_k]$ satisfies the conjecture, then their composition $F(g_1(x^1),...,g_k(x^k))$ satisfies the conjecture. As an application we show that the FEI conjecture holds for read-once formulas over arbitrary gates of bounded arity, extending a recent result [OWZ11] which proved it for read-once decision trees. Our techniques also yield an explicit function with the largest known ratio of $C \geq 6.278$ between $H[f]$ and $Inf[f]$, improving on the previous lower bound of 4.615

An analysis of the determinants of risk attitudes in Ireland and the United Kingdom

In this paper we avail of new data in studies of financial capability conducted separately in the United Kingdom and Ireland to model the determinants of individuals’ attitudes to risk. These risk attitudes are explored explicitly in the context of savings and investments and are modelled on the basis of socio-economic characteristics such as age, gender, region of residence and educational attainment. Furthermore, we explore the relatively complex relationship between risk attitudes and proxies of individual’s wealth levels in the context of potential reverse causation.
